DraygenDrop

Simple LAN file transfer. Server runs on WSL, clients run on Mac, Windows, or Linux — no cloud, no accounts, no browser required.

How it works

Mac / Windows  ──── HTTP ────▶  DraygenDrop Server (WSL)
                                       │
                                 ~/draygendrop/

Clients auto-discover the server via a UDP broadcast — no manual IP config needed after the first run.

Server setup (WSL)

pip install flask
python3 server.py

Output:

  ┌──────────────────────────────────────────────────┐
  │              DraygenDrop Server                  │
  ├──────────────────────────────────────────────────┤
  │  Address     http://192.168.1.50:7474            │
  │  Drop dir    /home/user/draygendrop              │
  │  Discovery   UDP :7475                           │
  └──────────────────────────────────────────────────┘

Options:

python3 server.py --port 7474        # HTTP port (default: 7474)
python3 server.py --dir ~/drops      # storage directory
python3 server.py --udp 7475         # UDP discovery port

Client setup

Mac / Linux

chmod +x ddrop
./ddrop --discover          # find the server, save address

Or copy to PATH:

cp ddrop /usr/local/bin/ddrop

Windows

ddrop.bat --discover

Or just: python ddrop --discover

Client usage

ddrop photo.jpg report.pdf       # upload one or more files (globs work too)
ddrop *.log                        # upload all .log files
ddrop -l                           # list files on server
ddrop -g report.pdf                # download to current directory
ddrop -d old_file.zip              # delete from server
ddrop --discover                   # re-scan LAN for server
ddrop -s 192.168.1.50:7474         # set server address manually
ddrop --server-info                # show saved server address

The server address is saved to ~/.draygendrop after --discover or -s, so you only need to do it once.

Files

File	Purpose
server.py	DraygenDrop server (run on WSL)
ddrop	CLI client (Mac / Linux / WSL)
ddrop.bat	CLI client wrapper (Windows cmd)
~/.draygendrop	Saved server address (auto-created)
~/draygendrop/	Default drop directory on server

Network ports

Port	Protocol	Purpose
7474	TCP/HTTP	File transfer API
7475	UDP	LAN auto-discovery

Windows firewall: if clients can't reach the server, add an inbound rule for TCP 7474 and UDP 7475 on the Windows host, or run the server with --port on a port that's already allowed.
